@julian This is a fantastic visualization. I haven't detailed it well in the early draft, but this is where I'm heading. You might implicitly endorse your server's account. Servers might endorse each other (after some vetting process). The scenario you described would make me your 3rd-level endorsement (to temporarily use LinkedIn vocabulary). Then after we go out for beers at FOSSY, we might endorse each other as 1st-level contacts. Others could use that as a stronger signal of who to trust.
